ABSTRACT:
A process for the production of aluminum characterized by the steps of chlorinating a material containing chemically combined aluminum and silicon with chlorine to produce aluminum trichloride and silicon tetrachloride, reacting aluminum trichloride with manganese to produce elemental aluminum and manganese chloride, reducing silicon tetrachloride to yield silicon, oxidizing the manganese chloride to produce manganese oxide, and reducing the manganese oxide with silicon to produce manganese which is recycled to the second step for reducing aluminum trichloride.
